SEED DROFPER.

Application filed February ention is to provide a seed dropping attachment for corn planters nexpcnslve construcseed, and in connecwhereby a predeterkind of seeds may be in each hill.

minednumber of each automatically plante into a number of independent compartments, and in connection therewith a single movable from each y the said delivering quickly changed to dropped in each therewith means where means may be easily and vary the number of seeds hill."

fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Figure 1 is a side elevation of my improved seed dropping attachment.

Figure 2 is a detail sectional View taken on the line 22 of Figure 1.

Figure 3 is a vertical sectional view taken through the lower portion of the seed box and the dropping mechanism.

Figure 4 is an inverted view of the seed plate.

Figure 5 is an inverted plan view of the bottom plate of the seed box.

Figure 6 is a bottom view of the bearing plate on which the seed plate rotates.

Figure 7 is a detail sectional view taken on the line 7-7 of Figure 2.

Figure 8 is a detail sectional View taken on the line 8-8 of Figure 2.

The numeral 10 indicates the runner frame of a corn planter which is provided with a dropping spout 11 of the usual construction. A droppershaft 12 is also provided 111 Sfiltl frame. Supported on one side of the frame 10 is a bracket 13, while on the other side of the frame 10 is a bracket 14. The brackets 14 and 13 carry the bottom plate 15 of the seed box which is circular and somewhat dished. Hinge members 16 are attached to the plate 15 and are pivotally mounted to the upper end of the bracket 18. The opposite 16. 1927. Serial No. 168,645.

side of the plate 15 is provided with a lug 17 which carriesa bolt 18, by means of which the plate 15 is clamped in a horizontal posi tion. The bolt 18 is provided with a thumb d upon the plate 15 is a seed box 20 having a cover 21. he seed box 20 is provided with a partition 22 which extends from its top to its bottom, the partition being secured in position by flanges 23 which are riveted in place. The partition 22 forms remaining filled with another kind of seed, such as corn, the space 24 being designed to receive smaller seed. such as soybeans. he compartment 24 is considerably snlaller than the in a hill as of corn.

The bottom plate 15 is provided with an annular slot 25 which communicates'with the mam compartment of the'seed box.- plate is also provided with an annular slot h communicates with the bottom of the auxiliary seed 'box 24.

Rotatively mounted beneath the bottom plate 15 is a seed plate 27 which is circular in formation and has its periphery provided with a series of notches 28. The provided with a row of seed pockets 32 supported he center of the plate is opening 33 to downwardly projecting lug 34 from the central portion of the plate 15. said lug terminating in a slightly contracted'port-ion 35 which is half semi-circular and. half rectangular. Supported beneath the plate 27 is a bearing plate 36 provided with an opening 37 for receiving the contracted portion 3a of the lug provided with an in position, tatively supports the said plate.

The under surface of the seed plate is provided with an annula r rib 39 so that the pocket portion 31 is thicker than that portion carryingthe pockets 32, said rib being designed to travel in an annular groove 40 in the upper surface of the bearing plate 36. The plate 36 is provided with an opening 41 which combe rotatively received on a municates yqith the spout- 11. Said opening is also arranged to communicate with both rows of pockets 31 and 32 of the seed plate. That portion of the seed plate above the spout 11 is closed. Said closed portion including pivoted dogs 42 for forcing the seeds from the pockets 31 and The closed port on 15 I I designed to ,be en- "aged by a plunger {29 pivotally mounted to t 4 e uppey endo f an e rm 30 seeuredto the shaft These parts are of the usual const 'nction, and arranged to impart an intermittent roery ma m st t th p at as h a m 30 is r nke By this arrangement it will be seen that seed corn-may be placed in the compartment ogt the seed box, while the auxiliary cornpantment may be fidlQiQlflY i-th a difierent kind of e .e as s y bean a d at as t s plat is ro ated, a i 'eeteriniaed um er of seeds will enter the pockets 3i ,and also a predetermined number of seeds will enter the pockets 32.

That portionof plate 27 supporting the )oekets32 is t, inner to reduce the size oi the pockets -32, on account of the beans being smaller in size than the grains of ,corn. As the plate is rotated, the seeds in each set of pockets will be delivered simultaneously :to the dropping spout 11.

The nnmberflof seedsdr-opped in each hill is determined by the size of ,the openings in the plate 27 which plate may be easily andquickly changed if so desired. by seleasing the thumb nut 19, and swinging the seed hopper to .position Where the bearing plate 36 is uppermost, after which !the bolt 38 may be removed, permitting the plates '2? and 86. together with 'ie ring 44. to be removed, after which anew seed plate may :be placed in position having dififei'en-t size pockets.

Thus it will be seen that I have provided a seed dropping attachment for corn planters of simple, durable and inexpensive construction, and so arranged that no change is necessary to adapt it to plant a number of different kinds of seeds simultaneously. All that is necessary, that the seeds be placed in the various compartments.

I ,claim as my invention:

1. In combination, a planter runner frame hmringa dropping spout, a pair of upwardly promotingbrackets carr ed by said t' 1'a1ne,'a seed ho); having a bottom plate pivotally mounted to one .ofsaid braclrets, means for detach-ably securing the seed hex to ,the other one of said brackets, said bottom plate being i e irl-et it Pa r of s mme gr oms a e ies s semina Inc s pr i ed with a d -ww ly es enfi s s he qa h s, th o e? e d e s d lug t swea i g 2 an: tract/ed portion of angular formation, a seed P a ta b/ mas-med th ey-l nd ieel r zt e ofsad h s, a h a i n le' s p e -t d on the angular portion of said lug .to support a d seed Plat sa e g Plate ha ng a p n in .wm se seti w s id spent. t pr jec e thwuel h d we xdly tending lug of said bottom plate to deta'chahly sup port said bearing? plate said seed plate, a hed i s te i ely ins l t th reirl yn ee asins na ans f d iia ly some??? sa t a i s a said seed plate, an means for engaging the teeth a sa d r ng ta in rmi ten Y e tiiis said seed plate.

In combination with a lanter frame, a seed ho having a bottom pl atmineans for pivotally mounting the bottom pilate to said planter frame, said qOhQQQI plate having seerneceiving openings and a downwardly projecting lug on its qentral portion, .a.seed plate pivot-ally mountedon gar l ug, a bearin 1 plate detach-ably supported beneath said seed plate. a toothed ring rotativelv mounted on said bearing plate, means {or detaohablyconnecting said toothed ring with said seed plate, and means diorsuccessiyely engaging the teeth of said ring .to impart intermittent rotary motion to said seed plate.
